IMPROVEMENT IN CONSTRUCTION OF CANE-JUICE BOXES.

Specification forming part of Letters Patent No. 25,354, dated September 6, 1859.

To all whom, it may concern/.-

Be it known that I, Louis TREGRE, of the parish of St. John the Baptist, and State of Louisiana, have invented certain new and useful Improvements in Cane-Juice Boxes, of which the following is a full, clear, and exact description,reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 represents an elevation of my im proved cane-juice box. Fig. 2 represents a sectional elevation of the same, and Fig. 3 represents an elevation of the valve or gate to separate the upper from the lower portion of the box.

The object of my improvements in canejuice boxes is to so arrange the box as to retain those impurities (such as mucilage, dirt, &c.) contained in the cane-juice as it is received from the sugar-mill while the purer parts of the juice are being drawn off from divided into two parts-an upper and lower by means of a tight door or valve, so that when the impurities in the cane-juice have settled to the bottom of the box the closing of this door cuts off the pure fromthe impure portions of the juice, by which means the pure parts of the juice are drawn off into the sugarkettles without disturbing the impure part in the chamber below.

By reference to the accompanying drawings my invention will be fully understood.

My improved cane-juice box in the present instance consists of a rectangular-shaped box, A, with sloping sides. WVithin a short distance of the bottom and around the interior is a projecting flange or rib, B,which forms a seat for avalve or door, which, when closed, rests on this ledge and divides the box into two chambers-an upper chamber, A, and alower chamber, A This valve or door in the present instance is independent of the box, and can be withdrawn and taken out. A coil of pipe surrounds the interior of the upper cham her, A, into which steam is introduced for the purpose of heating the cane -juice. A valve or cock in the side of the box opensa passage into the upper elamber, by which the clarified juice is drawn oft, and also a similar valve is provided for the lower chamber, A, to draw off the sediment.

The mode of operation is as follows: Thebox is filled with juice, the valve or door 0 being open or taken out,and a sufficient quan- 'tity of the bisulphate of lime is mingled with upper chamber is now opened and the clarified juice run off into kettles as low as the top of the valve without carrying with it any of the impurities in the lower part of the box, after which the lower faucet is opened and the impure juice is run OH.

I do not confine myself to any particular form in the construction of the cane -j uice box, or to the form, construction, or attachment of the valve to the box, provided it is so arranged as to divide, when required, the box into two chambers-an upper and a lowerto separate the impure juice when it settles to the bottom from the clarified juice above.

Having thus described my improvements in cane-juice boxes, what I claim therein as new, and desire to secure by Letters Patent, 1s

The method of separating the pure from the impure parts of the juice when the latter has settled to the bottom of the box, so that the pure parts can be drawn off without disturb ing the impure, by dividing the one from the other by means of a movable partition-valve, or its equivalent, arranged within the box, substantially as described.

In testimony whereof I have subscribed my name.
